Gold Coast bus attacker avoids jail time

A Gold Coast woman whose attack on an elderly, vision-impaired bus passenger caused national outrage last year has escaped a jail sentence.

Video of Larna Janet Watmough, 22, and her friend Layni Cameron attacking 77-year-old Paul Buttigieg on a bus in February 2014 went viral.

Watmough was subsequently given a two-month suspended sentence and ordered to pay $500 in compensation.

But former Queensland Attorney-General Jarrod Bleijie appealed against what he said was a "manifestly inadequate" sentence.

Judge Paul Smith on Monday said there was no doubt the attack was vicious and unprovoked and agreed the sentence was inadequate.

He increased the suspended sentence to six months, but Watmough will not serve any time behind bars after the judge took into account her genuine remorse, limited criminal history, employment and continued rehabilitation.

"I note that (Watmough) has been employed since the sentence; continues to report to the probation office; has paid the compensation ordered; and continues to see a psychologist," judge Smith said in a written decision on Monday.
